After Lin Du and the four of them entered the cave territory, they did not block the entrance of the cave this time, and walked directly along a dark cave road in front of them, and walked like this for about twenty minutes, and found that this cave was made of pure nature, and there were some small cave rooms on both sides of the cave!

It's just that Lin Du and the others feel that something is more and more wrong, not only is the temperature of the cave gradually rising, but also when bursts of hot air blow in their faces, their bodies also feel hot and painful. Pen ~ fun ~ pavilion www.biquge.info.pbx.m

"Wait!"

Lin Xunjia and the three of them stopped when they saw Lin Du's footsteps in front of them, and suddenly spoke, and stopped with a little solemn face.

"Childe, did you find out something?" Lin Xunjia opened his eyes vigorously, but he still couldn't see anything wrong with a black hole in front of him!

"The situation is not, but this kind of place is really a bit weird, let's not move on first, you just cultivate here, take out the demon beast Yuanjing and spirit grass on your body, and I am going to refine the pill for you."

Lin Du searched for a while with his spiritual sense, and thousands of miles away, he still found that there was no living thing, and his face relaxed a little, but there was always a faint feeling of a very bad feeling in his heart, as if an unknown danger was coming.

"Good ......"

Lin Xunjia and they nodded in response, seeing that Lin Du's face was a little heavy, they didn't dare to ask anything more, everyone hurriedly took out the materials and handed them to Lin Du.

Lin Du explained, then took all the materials and walked into a cave in front of him, and Lin Xunjia and the three of them also picked a cave room to go in to cultivate.

……

Inside the cave, Lin Du took a breath, sat cross-legged on the ground, meditated for a while, and immediately activated the spiritual energy in his body, and in an instant, a purple flame in his palm floated up. pbx.

His eyes swept the wind pattern stone tripod hovering in mid-air, and the flame in his palm spit out slightly, and a ball of spirit yuan flame fell into the danding, surging and surging, and all of a sudden, the hole was bright.

With that, Lin Du grabbed several spirit grasses in front of him with his palm, and immediately threw them into the stone ding.

Purple dragon cloud grass, phoenix condensation fruit, silver leaf dew, heaven and earth spirit ginseng into the flame of Danding, it was quickly burned, a breath of effort, the four materials have been burned into a bunch of black and white two-color liquid, a black and white liquid smart and wonderful around the top of the Danding.

With the strong forging of the Lingyuan flame in the Danding, Lin Du once again condensed his mind, controlled the temperature of the Lingyuan fire, and in a moment, immediately entered the next step to remove the slightest impurity in the black and white liquid.

After successfully and perfectly expelling the liquid impurities, Lin Du smiled slightly, and spit out a trace of spiritual energy from his palm and sent it into the Danding, and the Lingyuan flame in the Ding exhaled, and then surged up.

At this time, under the fierce burning of this suddenly strong surging Spirit Yuan flame, the four bundles of black and white liquid floating above the Danding immediately melted together, and in a moment, it had completely solidified into the shape of a pill the size of a red bean.

The step of fusing the spirit grass liquid was successful, and Lin Du quickly poured out the four first-level demon beast Yuan Crystals from the medicine bottle, and then threw them into the Danding.

As soon as he entered the fierce flames, he was calcined into a bundle of reddish liquid in an instant, and then, Lin Du continued the refining process step by step, picking out impurities, refining, fusing liquid, and refining into a round pill shape!

In the end, Lin Du fused the black and white condensation pill floating above the Danding with the reddish round body pill refined by the demon beast, and as soon as the condensation of the two different colors touched, there was a slight sound of resistance!

In an instant, Lin Du still maintained the high-speed transmission of spiritual energy, and the two pill condensations that had gradually merged into one continued to float within the Danding, and the strong flipping made a soft sound of collision in the Danding.

Twenty minutes later, when the spiritual energy in Lin Du's body gradually weakened, a flat round Dan shape the size of a thumb had already appeared inside the Danding, and it was slowly rising within the Danding.

Lin Du said lightly: "The following are the steps to cultivate the round pill!" ”

After cleaning up the distractions, Lin Du glanced at the oblate body pill above the pill, smiled knowingly, and as soon as the spiritual energy in his body was released, it was immediately enveloped, and then, a peaceful aura was constantly surrounding the oblate body pill, swirling non-stop.

A few minutes later, when the cultivation step of the spiritual breath energy came to an end, Lin Du looked up and saw that an elixir with a smooth and round surface, a scattered side of the pill incense, and a thick black and white and reddish light finally came out.

Lin Du was slightly surprised when he saw this three-colored elixir, he didn't expect such a strange phenomenon to appear, the blood-red demon beast Yuan Jing was not melted by the black and white liquid, and the surface of the elixir had an extra color!

Temporarily letting go of the slightest surprise in his heart, Lin Du continued to warm the pill in the flame for a few minutes before extinguishing the Spirit Yuan flame in the Danding.

When the flames were extinguished, Lin Du shouted softly, "Get up!" As soon as he grabbed the medicine bottle prepared on the ground, he stretched out his hand, and the pill that Teng Chong came out of Danding fell into the medicine bottle slightly steadily.

"Dragon and Phoenix Mixed Pill! An intermediate-grade high-grade pill is just right for Brother Lin's Heavenly Realm cultivation. It's just that the Dragon and Phoenix Mixed Pills are one black and one white Dan color, and now there is a reddish tinge, and I don't know if the effect is increasing or weakening......"

……

With that, Lin Du exhaled, this one has been completed, and next, he will refine a pill for Lian Ziyi and Zhang Yi respectively.

Without further ado, Lin Du pondered for a while, and immediately entered a meditative state again, and after half an hour, he replenished the spiritual energy consumed just now, and continued refining again!

Looking at the spirit grass in front of him and the bottles of first-class demon beast Yuan Jing, Lin Du smiled slightly, thinking to himself, it was really the first time that so many materials were placed for himself to refine, and then he muttered: "The feeling of having materials is really cool, if you want to refine, you can refine it!" ”

Below, for nearly an hour, Lin Du not only did not appear tired, but the more he refined, the more energetic he became, throwing away the materials, burning them in the Danding, refining them into liquids, and removing impurities......

The step-by-step refining process, in Lin Du's agile hands, was carried out perfectly and vividly, and the movements could be described as smooth and smooth in one go, without the slightest pause......

"Close!"

At this time, when Lin Du let out a low drink, there was a clang, and when a pill fell into the medicine bottle, the third pill was also announced to be successfully refined!

"Silkworm Pole Dan! The intermediate-level mid-grade pill, fortunately, there are enough first-level demon beast yuan crystals, otherwise, if you think that the main material is refined, it can only be an intermediate-grade low-grade pill. ”

Lin Du looked at the second pill that had been refined, nodded with satisfaction and said.

"Lielian Pill! It's a pity, if it's not lacking, it must be an intermediate-level high-grade pill, but, now it's good, with the assistance of a few bottles of first-level demon beast Yuan Jing, it finally didn't fall to the rank of the lower pindan, and finally stabilized at the grade of the intermediate-level mid-pindan. ”

Lin Du looked at the last pill and muttered helplessly.

In a moment, Lin Du took the three pills he had refined, packed up the remaining materials, and walked out of the cave!
